SPI Status Control Registers Tab Panels

Each SPI Status or Control Register is arranged in its own panel. Each of the sixteen panels display the possibilities for the
appropriate register. Access to the other tab panels is possible by clicking on the abbreviated register names, located above and
below the panel.

Table 5-1. Generic Control User Helpful Page Description

The Control SPI Registers tabs give a basic view on the functionality of the MC33912 device
and allows the use of these functions. The Status SPI registers tabs show possible states of
the MC33912 device and indicate their status.
quick system status overview. It summarizes the status of the Voltage Status Register VSR,
LIN Status Register LINSR, High-Side Status Register HSSR and the Low-Side Status Regis-
ter LSSR.
System status registers indicate the state of MC33912 device.
when a user drags and releases a mouse button. Frequency range of the Pulse Width
Modulation is selectable by a drop-down menu.
These two buttons show the SPI Watchdog clear time and offer a switch off for the Watchdog
clear routine.
If in communication an error occurs, then the error message is shown in the first white area.
If the user chooses one of the wake-up capabilities and the wake-up event isn't configured
correctly, then user is given a notice on what to change to configure the wake-up properly. This
message is shown in second white area.
If a reset condition is detected, then the user is warned and the control page reverts to the
default state and the reset flag is displayed in the third white area.
The Graph indicator shows analogue voltage from the ADOUT0 and ADOUT1 outputs. The
blue line indicates the voltage on the current sense input in mV, and the blue label calculates
the current through the resistor connected to these inputs. A second line shows the variable in
accordance with the Multiplexer Control Register MUXCR. The actual source of the voltage is
displayed in the red caption of the Graph, and the appropriate axis is readjusted to the actual
units.
The section shows three wake-up sources and helps the user to correctly set-up one of the
wake-up events.
The Variable Watch Pane displays the variables assigned to the watch. It displays the current
variable values and allows user to change them (if enabled in the variable definition). See
FMASTXXX.pdf document available at http://www.freescale.com.
Clicking the Back button will open the Welcome screen.
The Sequence Pane allows control in executing the command sequence.
